wishawa··on Crystal arrangement results in more power from ferroelectric solar cells
I did a quick Google for the Power Conversion Efficiency of Barium Titanate based solar cells and they are currently mostly in single-digit percentages [1]. A thousandfold increase would be over 1000%. Unless I'm missing something important, they probably mean 1000x over a super basic BaTiO3 system, not 1000x over the current state of the art.

[1] For example, this 5.13% PCE from "hierarchical barium titanate micro flowers": https://iopscience.iop.org/article/10.1088/2053-1591/aace86

wishawa··on GAN-generated facial images that are capable of impersonating multiple IDs
Another important question is is it really a magic face they found, or just a magic image of a random face? If they managed to build an adversarial GANs that work on the object rather than a digital image of one that would be interesting enough on it own.

They're beating facial recognition systems, not facial authentication systems.
wishawa··on Reducing CO2 emissions by targeting the world's hyper-polluting power plants
> unsurprisingly many of them are in China and India Of the ten plants just one is in China and two are in India.

South Korea, having three, might be a better target here.

I agree that Germany should set an example. The German plant is 40 years old already anyway.

Other countries with newer plants would be more reluctant.

wishawa··on Language records reveal a surge of cognitive distortions in recent decades
The phrases are proven/believed to correlate with Cognitive Distortions, but that is when they are used in conversations, or diaries, or maybe short writings. Not in books, which are very different from those things. Doctors don't ask a patient to write an entire book and count these phrases to determine whether or not the patient have Cognitive Distortion.
